Title: Enciphering method
Inventor: KATSURABAYASHI MASAHIKO
IPC: G09C1/00
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To perform partial enciphering without being limited by the data of processing object. SOLUTION: The plane sentence of object is partitioned in the unit of 8 bytes. A plane sentence M0 and an initial vector V are exclusively ORed (T1) and DES enciphering is performed (T2). The enciphered result C0 is defined as an enciphered sentence C0 corresponding to the plane sentence M0 . Concerning following blocks, the plane sentence of relevant block and the plane sentence of preceding block are exclusively ORed without DES enciphering (T3 and T4) so that the enciphered sentence is provided. In order to provide the non- enciphered plane sentences of blocks after the 2nd one at the time of deciphering, concerning all the blocks preceding to the relevant block, it is necessary to successively provide plane sentences from the leading block and to repeat exclusive ORing.  Namely, when deciphering any block, first of all, the DES deciphering of leading block (T5) is required at all the time. Besides, since data are enciphered for the unit of a block composed of fixed 8 bytes while using chain techniques, enciphering is not limited by the data type of processing object.

Abstract: PURPOSE:To always ensure a high speed arithmetic processing operation by repeating the arithmetic processing operation for each prescribed digit together with acquisition of the information showing the negative arithmetic result and carrying out a correcting operation according to the presence or absence of the negative information. CONSTITUTION:An arithmetic logic unit ALU 15 contains four subtraction circuits 15a - 15d arranged in parallel with each other.
